I agree with Koen when he says that formatting should be done in the visualization layer.

But if the column type is money, then you can use CONVERT and a format code.

money and smallmoney Styles

When expression is money or smallmoney, style can be one of the values shown in the following table. Other values are processed as 0.

Value Output

0 (default) No commas every three digits to the left of the decimal point, and two digits to the right of the decimal point; for example, 4235.98.

1 Commas every three digits to the left of the decimal point, and two digits to the right of the decimal point; for example, 3,510.92.

2 No commas every three digits to the left of the decimal point, and four digits to the right of the decimal point; for example, 4235.9819.

For example:

SELECT CONVERT( varchar(15), MyColumn, 1)
